OECD Guidelines for the Testing of Chemicals, Section 4

Health Effects

The OECD Guidelines for the Testing of Chemicals is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. They are a set of tools for professionals, used primarily in regulatory safety testing and subsequent chemical and chemical product notification, chemical registration and in chemical evaluation. They can also be used for the selection and ranking of candidate chemicals during the development of new chemicals and products and in toxicology research. This group of tests covers health effects.

This Test Guideline describes an in vitro assay, which provides concentration-response data for substances with in vitro ER agonist and antagonist activity. The test system utilises the BG1Luc4E2 cell line derived from a human ovarian adenocarcinoma ...

This Test Guideline describes an in vitro screen for chemical effects on steroidogenesis, specifically the production of 17ß-estradiol (E2) and testosterone (T). The human H295R adreno-carcinoma cell line, used for the assay, expresses genes that ...

The basic principle underlying the Local Lymph Node Assay (LLNA) in mouse is that sensitizers induce a primary proliferation of lymphocytes in the auricular lymph nodes draining the site of chemical application. This proliferation is proportional to ...

The Local Lymph Node Assay: DA (LLNA: DA) is a non-radioactive modification to the LLNA method for identifying potential skin sensitizing test substances and measuring the proliferation of lymphocytes they induce in the auricular lymph nodes. The ...

The method described by this Test Guideline provides information that allows hazard assessment for short-term exposure to a test article by inhalation, and allows the substance to be classified according to the Globally Harmonized System of ...

The Hershberger Bioassay is an in vivo short–term screening test. It evaluates the ability of a chemical to elicit biological activities consistent with androgen agonists, antagonists or 5 á-reductase inhibitors. The current bioassay is based on the ...

This method provides information on health hazard likely to arise from exposure to test substance via oral administration. The method is based on the repeated oral administration of the substance of interest during one limited period (one dose level ...

The method permits estimation of an LD50 with a confidence interval and the results allow a substance to be classified for acute toxicity according to the Globally Harmonised System of classification and labelling of chemicals. It is easiest to ...

A developmental neurotoxicity study will provide information on the effects of repeated exposure to a substance during in utero and early postnatal development. The test substance is administered daily, generally orally, to mated females (rats are ...

The Uterotrophic Bioassay is an in vivo short-term screening test. It is based on the increase in uterine weight or uterotrophic response. The Uterotrophic Bioassay relies for its sensitivity on an animal test system in which the ...

The in vivo percutaneous absorption study set out in this Test Guideline provides the linkage necessary to extrapolate from oral studies when making safety assessments following dermal exposure. The in vivo method, described in this guideline ...

This Test method has been designed to provide information on absorption of a test substance, (ideally radiolabelled), applied to the surface of a skin sample separating the two chambers (a donor chamber and a receptor chamber) of a diffusion cell ...

This Test Guideline describes a method to evaluate photo-cytotoxicity by the relative reduction in viability of cells exposed to the chemical in the presence versus absence of light. Balb/c 3T3 cells are maintained in culture for 24 h for formation ...

A principle of the method is that in the main study only moderately toxic doses are used, and the administration of doses that are expected to be lethal should be avoided. This Guideline is intended primarily for use with rat. Groups of animals of a ...

This Test Guideline for two-generation reproduction testing is designed to provide general information concerning the effects of a test substance on the integrity and performance of the male and female reproductive systems, and on the growth and ...

This method provides information on health hazard likely to arise from short-term exposure to test substance. The determination of sub-chronic oral toxicity using repeated doses may be carried out after initial information on toxicity has been ...
